Narrow veins are major sources of many commodities, including gold, silver, tin, tungsten, coal, uranium and sometimes copper, lead and zinc. Mining this narrow style of mineralization can be considered as relatively high risk, not only due to the high cost of exploration and mining per unit of metal, but also to the frequently limited size of ...
With a focus on mine grade, Mako's objective was to utilise narrow vein expertise and equipment for ore driving and stoping, whilst RUC's ability to deliver on large scale development, haulage and raise boring services ensured all bases were covered.
The mining methods used at the Dome Mine are longhole, room-and-pillar and cut-and-fill. It is significant to note that, actually, all narrow veins are mined out using the cut-and-fill method. The economics .
DL210 is a compact and flexible electro-hydraulic longhole drill rig engineered for production drilling in narrow-vein underground mines. The rig is designed for .
Conventional narrow vein mining, utilising hand held methods, is expensive and requires specialised miners who are becoming a rarity. Hand held mining techniques (shrinkage stoping, leading stoping and cut and fill) have the advantage that they can be selective. The methods allow continued sampling of the face, control of hanging wall conditions and are adaptable...
The mining industry is continually looking for ways to automate and mechanize its operations. This presents a great challenge for narrow-vein operations. The actual mining parameters and existing mechanized equipment make profitability difficult to achieve.
